Grizzlies:
They add all-star talent in their prime and in a really friendly contract and some 3 and D presence on the frontcourt. Memphis is one of the best fits for Sabonis considering how athletic they're on defense and that they could use Domas playmaking to give opponents a different look during games. They're also solving a little of a future issues they can have by sending some of their expirings around and finally making a decision between Clarke and Tillman.
Pacers:
They get a haul of picks while reseting their cap and roster makeup. I honestly think not getting 1 or 2 really good prospect is a good thing for Indiana going into the draft because it'll likely make it easier for them to draft a player without thinking too much about a fit. Imagine the scenario that they trade Sabonis for a young and high ceilling PF and then comes the draft and they fall in love with Banchero or Smith and they're in a position to draft one of them. By receiving picks instead of prospects it'll ease their decision making and roster building going into the offseason.
Mavs:
Dallas add a player that can help their offense with high IQ, all-around game and high quality passing in a foward rotation that lacks exactly that.
Celtics:
Jones is a player that Boston don't have, a smart enough PG that can both run the offense or play off the ball when needed, he can be a great contrast to what Schroder brings to the table and make them more flexible depending on matchup.
Bulls:
Bulls get a cheap contract and a player that's urging for play time in a situation that he'd fit right into their rotation on their playoff run.
